- IMPROVEMENT IN PINKVING-MACHINES.

The Schedule referred .to in these Letters Patient and making part of the same.

To all whom it mag/'concern Be it known that I, FRANCIS L. HAGADORN, of the'city of Baltimore, iurthe'State of ltaryland, have invented a new and improved Method of linking or ornameuting the edges ot' leather, cloth, silk, and

other fabrics; and I do hereby declare that the fol# lowing is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing a circular knife, A, corrugated into any given figure, and adjustedhy the screws I I in the fraxne G C C, so as to ply upon the wheel B.

The circular knife A and the cog-wheels G H, are secured between the two slides D D.

The crank E is attached to the axle of the cogwheel G. i

The feeding-hoard Fis secured to the frame by a pin and screw, and the table-screw K holds the entire machine to the top of any ordinary table-shelf or workbench.

Y To enable others skilled in the art to make and use my invention, it is only necessary to add that power may be given to it by meaus'of belts land pulleys, instead of the crank E; that the shaft L L may be indefinitely extended, and the circular knife A duplicated to any desired extent, and arranged upon it.

The knife A and the wheel B are also capable of a vibratory movement, although not shown in the accompanying drawings.

The knife A should be madeof superior steel, and the wheel of wood, lead, copper, or other soft material.

What I claim as my invention, and desire to secure by Letters Patent, is-
